Vas Deferens and Seminal VesiclesOnce sperm are produced, they travel through a collection area, called the epididymis, and then through a tube or duct, called the vas deferens, which then joins the seminal vesicles to form the ejaculatory duct. The seminal vesicles produce a fluid that provides nutrients for the sperm and lubricates the urethra. This fluid mixes with other fluids to create the semen. During ejaculation, muscles surrounding the seminal vesicles contract and push out the sperm and the fluid from the seminal vesicles, much like squeezing a tube of toothpaste. The seminal vesicles are located behind the prostate and the bladder. |
